On the Computational Hardness Needed for Quantum Cryptography

In  the classical model of computation, one-way functions (OWF) are arguably minimal for computational cryptography,  namely  they are essential for almost any cryptographic application that can only be realized with respect to computationally bounded adversaries. In the quantum setting, however, OWFs appear not to be essential (Kretschmer 2021; Ananth et al., Morimae and Yamakawa 2022); in particular,  no  minimal  primitive is known.
